随着社会的发展、生产的扩大,为了实现更好地生产,化工操作工要熟练操作设备,并且做好设备的维护,减少生产损失,这样就可以减少检修带来的人力物力及停滞生产所带来的利润损失.在化工生产中主要有换热器、压缩机、冷冻机及泵,在此主要以冷冻机为例,介绍冷冻机的原理、组成、开车准备、操作、遇到积液的判断与处理,不断提高操作人员对冷冻机的操作,保护好设备并减少对设备的损伤.%With the development of society, the expansion of production, in order to achieve better production, chemical operators must operate equipment expertly, and do a good job on equipment maintenance to reduce the production loss, which can reduce the manpower and material resources as well as loss of profit brought about by the stagnation production. In the chemical production, it mainly has heat exchanger, compressor, refrigerating machine and pump. In this paper, taking refrigerating machine as the example, its principle, composition, preparation of driving, operation, as well as judgment and treatment when encountering hydrops were introduced, so as to constantly improve the operation of operators to refrigerating machine, protect the equipment and reduce the damage to the equipment
